Water Damage from Car Cover

[prowlinpassion]

Hi,
I have a 99 Purple Prowler which is left outsde with an Evolution 4 car cover and with a tarp over the cover. I took both off only to discover a large stain, milky-colored (about the 15" diameter)on the hood. I brought to a detailer who attempted to buff it out, without luck. I then brought it to a body shop, who has rarely seen this, but talked about the stain baking through and possibly attacking the clear coat, and would need to refinish the hood. Any ideas on commercially available cleaners I can try before going through this hassle and expense? Any suggestions are welcome! Here is the url for the pictures:

It would really help if you had some pictures. Can you feel the stain? Is is raised, lowered, rougher than the un-stained area? Also, the Evolution covers are breathable, if the tarp you had on top was not, that is probably not the best practice. Some members here use combinations of two car covers, with both I believe being breathable, perhaps they will chime in (Bill D, where are you?).

Hi Mike,
Thanks for the reply. My pics are to 'large' to attach. If I can send them to via e-mail I would be happy to. Please send me your e-mail. Appreciate your help.
Best,
Ron

I've seen this exact condition previously. It appears the moisture has somehow permanently damaged the paint. I thought it would go away but I saw the car several months later (he ceased using the car cover) but the white "cloud" was still there, pretty much unchanged.

(This is one of the reasons I'd NEVER use a car cover on a car kept outside.)

The reason this happened is becuase you put a tarp over the car cover. The car cover needs to breath and by putting the tarp over it it could not breath. Its not the car covers fault, its the tarps fault.

Prowlin, there are many photo tools which would allow you to resize those photos so they are small enough to post, then everyone can see them.

Many times placing the car out in the sun will evaporate the moisture. Clear coats will absorb a rather large amount of water and also release it BUT as noted because air was not allowed to circulate because of the tarp it may be beyond coventional repair.

Rubbing alcohol can aide in evaporation but let it sit in the sun for a day and see what happens. Re-paint might be the only solution if not.

Yuk, that's bad. Identical to what I witnessed on my friend's car.

Permanent damage. Just like what people get under their vinyl bras when they leave them on for months on end in areas that see rain.

It will improve some baked out in the sun for a few weeks. But the only real fix is a repaint.
